Playing in the park, Zee follows the squirrel through a portal to another world, populated with shadows. Surrounded by unknown creatures, you should avoid getting into the section between dimensions, go on a journey of discovery and awakening. Explore 77 levels in 6 unique worlds, each with its own secrets. Blocks should be balanced and react to gravity. Interaction with the environment includes falling rocks and spikes, which grow on contact with the echo of Zee.
